Abstract: This invention concerns a process for fluorinating a perfluoroelastomer which has previously been crosslinked by exposure to ionizing radiation. The resulting product has reduced outgassing. This makes perfluoroelastomer parts that have undergone the process particularly useful in clean rooms and for semiconductor manufacturing.
